Project Set-up Checklist

If you want to get started using the template, here's a step-by-step checklist to follow to kickstart the project.

  • Go to and purchase the codebase.
  • After completing the purchase, you'll receive an email with the download link.
  • Unzip the codebase and open it with Visual Studio Code

You can run the app in development mode straight out the box.

However, to connect with external services (e.g. auth, database, maps, etc), you will have to configure the project. Don't worry, you dont't have to modify the codebase, all these features are already implemented.

You just have to connect the app with your accounts (e.g Firebase, Stripe, etc.), and you can follow the steps described down below.

Bundle ID

The first step is to modify the bundle ID. Each of our template bundle ID starts with "com.atomsbox", our reverse domain name. You'll have to replace it with your own reverse domain name.

In Visual Studio Code:

  • Choose your bundle ID. Use your reverse domain name or whatever identifier you prefer.
  • Search and replace "com.atomsbox." --> How to search and replace in VSC

Environment Variables

EchoLink has two files containing the environment variables:

  • The client-side environment variables are stored in the .env.example (rename it to .env).
  • The server-side environment variables are stored in the api/.env.example (rename it to .env).
# Client-side .env
# Server-side .env

To complete the list of environment variables, you'll have to configure Firebase.
